I dont count Matsui as a developed player considering the fact that he played in Japan before he came to the Yankees. He didnt even go through the farm systems. Those four names in Cano, Posada, Jeter and Joba are pretty good names but IMO they dont come close to those of the Sox or even the Rays. The Sox list inculdes Dustin Pedroia(who in just two years has already became ROY and MVP), Kevin Youkilis, Jed Lowrie, Jacoby Ellsbury, Justin Masterson, Clay Buchholz (who has thrown a no-hitter), Jonathan Papelbon, Jon Lester (who has thrown a no-hitter.)
